I’m in Dallas for a business event. I decided to drive up, rather than deal with airlines and security and all that hassle. Average travel time by air is 1 hour. Add in 1.5 hours at the airport, and a 3.5 hour drive starts to look pretty attractive. A good way to get a feel for the size of Texas is to drive across it. A good way to get a feel for Dallas Fort Worth airport is to note that it’s larger than the whole of Manhattan island.
